Playing with the Symfony2 serializer

New way to set the encoder.

<?php

// Inside your action

$this->serializer = new \Symfony\Component\Serializer\Serializer();
$this->serializer->addNormalizer(new \Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer());
$this->serializer->setEncoder('xml', new \Symfony\Component\Serializer\Encoder\XmlEncoder());

return $this->createResponse($this->serializer->encode($page, 'xml'), 200, array('Content-Type' => 'application/xml'));
